Patent JP-S6110242-A (JP)
Title: Film for processing silicon wafer
Inventor: NARIMATSU OSAMU
IPC: C09J7/02
Filed: 1984-05-29
Abstract: PURPOSE:To obtain films for preventing damage used in polishing Si wafers and the like by a method wherein a substrate film having a specific hardness is stuck to the wafer surface via self-adhesive. CONSTITUTION:As the substrate film, a film made of thermoplastic or thermosetting synthetic resin or natural or synthetic rubber having a Shore D type hardness of 40 or less preferably 30 or less can be suitably selected out of marketing products. A hardness of over 40 can not substantially prevent damage in wafer polishing. As the self-adhesive provided on the surface of the substrate film, a self-adhesive e.g. of acrylic, ester, or urethane series or a self-adhesive of synthetic rubber series which is normal one in market can be used. This film is abundant in flexibility and has the property of absorbing and dispersing the outer force; therefore, polishing the back by sticking this film to the wafer surface can prevent wafer damage.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for an expensive pressure regulator and to select the supply pressure of a carrier gas arbitrarily by connecting a channel resistor with a pressure sensor and a differential pressure sensor and a control valve to a canier gas supply channel. SOLUTION: A control part 9 stores an expression Q=K×P1×ΔP inside and the pressure P1 that is measured by a pressure sensor 21 is constantly inputted into the expression. In the expression, ΔP is the flow rate of a carrier gas, K is a coefficient that is determined by a resistance pipe 3, P1 is a pressure at the upstream of the resistance pipe 3, and ΔP is a differential pressure that is measured by a differential sensor 4. The control part 9 obtains a differential pressure (ΔPSET) corresponding to a desired flow rate and sends a signal to a control valve 5 so that a differential pressure that is measured by the differential pressure sensor 4 becomes ΔPSET. A carrier gas whose flow rate is controlled by the control part 9 carries a sample that is introduced to a sample introduction part 6 to an analysis column 7 and a sensing part 8.  After the sample is separated from an analysis column 7, it is determined qualitatively and quantitatively by the sensing part 8.

Title: Brushless motor
Inventor: ITO MOTOYA
IPC: H02P6/08
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a brushless motor capable of reducing the cost of a drive circuit and reducing switching noise. SOLUTION: A five-phase brushless motor is energized at a four-phase armature coil by switching MOSFETs 36-45 using a parallel path. The current passing through the MOSFETs 36-45 becomes one half that of the conventional three- phase full-wave driven system, so that the respective MOSFETs 36-45 can use an inexpensive element having lower current capacity. When exciting phases are switched, one of two exciting phases is turned off at one exciting path of the parallel paths, and one non-exciting phase is turned on. As a result, the change in the total current of the motor become low in switching exciting phases, so as to reduce the switching noise. When required rotation speed is low, the motor torque is reduced to cause the rotational speed of the motor to be reduced by energizing only two-phase armature coil (two-phase energization).  As a result, the rotational speed of the motor can be made variable without conducting PWM control.
